Objective To understand the risk factors of neurogenic pulmonary edema in the patients with severe hand foot and mouth disease(HFMD). Methods According to neurogenic pulmonary edema or not ,79 patients with severe HFMD were divided into two groups. The difference was analyzed on the clinical symptoms, signs,the outcomes of laboratory and electroencephalogram (EEG) examination between the two groups. Then the risk factors of neurogenic pulmonary edema was analyzed by logistic regression analysis.Results There were significant differences of the EV71 infection rate,high body temperature,myoclonia,limb weakness,the disability of eyeball regulation,tachycardia, hypertension or hypotension, the extension of capillary filling time, leucocytosist, creatine kinase isoenzyme, hyperglycaemia between two groups. However, there were no significant differences of fever, fever time, vomiting, somnolence, convulsion, limb tremor, c-reactive protein and EEG between two groups. Tachycardia, hypertension or hypotension, hyperglycaemia were significant risk factors for neurogenic pulmonary edema by logistic regression analysis. And hyperglycaemia was the most significant prognostic factor(odd ratio 27. 075, P = 0. 000 2). Conclusion Tachycardia, hypertension or hypotension,hyperglycaemia are the significant risk factors for neurogenic pulmonary edema. It is especially important for hyperglycaemia to predict neurogenic pulmonary edema.

Objective To explore the feasibility and safety of early ambulation in patients with acute deep ve-nous thrombosis. Methods The literatures about early ambulation for acute venous thrombosis were collected and the quality of the literature was evaluated by two investigators independently. Results Thirteen published studies were recruited for systematic review,including 10 RCTs and 3 CCTs. The meta-analysis showed that compared with bed rest,early ambulation did not increase the incidence of secondary pulmonary embolism in patients with acute DVT[early activity:22/1408;bed rest:34/1417;RR=0.62,95%CI(0.37,1.03),and the incidence of DVT progression [early activity:48/1523;bed rest:45/1525;RR=0.85,95%CI(0.58,1.24)]. There were no statistically significant differ-ences in mortality,swelling,and pain relief in acute DVT patients. Conclusion Early ambulation did not increase the incidence of thrombus progression and secondary pulmonary embolism in patients with acute DVT compared with bed rest. Besides,early ambulation cannot relieve symptoms of swelling and pain in DVT patients. However,it can relieve the acute pain of DVT patients with moderate to severe pain.

Objective:To study the relationship between genetic polymorphisms of GSTM1 GSTT1 and the susceptibility of laryngeal and hypopharyngeal carcinomas(LHC).Method:The GSTM1 an GSTT1 genotypes were determined by multiplex PCR analysis in 76 LHC patients and 76 population controls.The association be tween the genotypes and LHC risk was measured by odds ratios(ORs)and 95% confidence intervals(95%Cls).Resuit:The frequency of GSTM1 null genotype was 59.2% in the LHC patients and 42.1% in controls(OR=1.935,95%CI=1.069-3.510),the difference was significant(P＜0.01).The frequency of GSTT1 null genotype was 57.9% in the LHC patients and 51.3% in controls.The difference was not significant(P＞0.05).In smokers,the risk of the LHC increased in subjects of GSTM1 null genotype(OR=5.545,95%CI=2.158-13.528).Conclusion:GSTM1 polymorphisms are associated with susceptibility to the LHC.It has the synergistic effects with smoking in the development of the LHC.GSTT1 genotypes might have no association with risk of the LHC in urban Linyi.

Objective To study the variation and characteristics of HIV-1 tat exon 1 gene from a patient with AIDS dementia complex( ADC), so as to research the pathogenesis of ADC. Methods The tat gene was amplified with nested PCR from genomic DNA which was extracted from lymph node, spleen and different brain tissues( meninges, grey matter from frontal cortex, white matter from frontal cortex, temporal cortex and basal ganglia) of a patient who died of ADC. PCR products were cloned into the pGEM-T vector,after transformation and selection by ampicillin and blue/white spotting. Five of positive clones were sequenced. HIV-1 tat sequences were processed with BioEdit and MEGA4. With the softwares, Neighbor-Joining tree, p-Distances, values of ds/dn, and analysis of amino acid motifs were all done. Results The samples were all identified as HIV-1 B and genetic variation exists in HIV-1 tat isolated from different tissue;Compared with HXB2, sixteen sites of the amino acid seque nce coded by the HIV-1 tat gene which was isolated from the patient changed. In addition, part of the changes were different between periphery and brain,especially, the five Q54R changes from basal ganglia and one Q54R change from temporal cortex are deserve to follow with interest. Conclusion Variations exist in the HIV-1 tat genes extracted from the ADC patient and the variations from peripheral and central nerve tissues were different, whether the variations concerned with the pathogenesis of ADC need more research.
